Method for preparing calcium silicate board by using deeply reduced copper smelting slag
The invention discloses a method for preparing a calcium silicate board by using deeply-reduced copper smelting slag, which comprises the following steps of: crushing the deeply-reduced copper smelting slag serving as a main raw material, adding sodium sulfate for ball-milling and activating, mixing with fiber and water to form slurry, preparing a blank from the obtained slurry, and performing steam curing to obtain the calcium silicate board. According to the preparation method, the copper smelting slag can be recycled, resource waste is reduced, pollution of the copper smelting slag to the environment is reduced, the preparation process of the calcium silicate board is simplified, and the prepared calcium silicate board has the excellent performance of high purity, high strength, water resistance, fire resistance, crack resistance, sound insulation, shock resistance and the like and can be widely applied to the field of building decoration.
本发明公开了一种利用深度还原铜冶炼渣制备硅酸钙板的方法，其是以深度还原的铜冶炼渣为主要原料，将其经破碎，加入硫酸钠球磨活化后，与纤维和水混合形成浆液，再将所得浆料制得坯体，通过蒸汽养护，制得所述硅酸钙板。本发明不仅能够循环利用铜冶炼渣，减少资源浪费，减少铜冶炼渣对环境的污染，还简化了硅酸钙板的制备流程，且制备的硅酸钙板具有纯度高、高强度、耐水、耐火、抗裂、隔音、防震等优良性能，可以广泛应用于建筑装饰领域。
